SPECIFICATION forming part of Letters letent No. 671,679; dated April 9, 1901.

MM.i dustries,1 Serial No. $7,775. (Ho modnLl' V To all 'wlm'iit may concern: I Be it known" that LWILLIAM ORR, a citizen oflthe IUnite-d Stntes,,rcsiding at Trenton, county of- Mercer, and State of New Jersey, haveinvented certain new and useful Im- V proveme'nts in Fireproof Constructions, fully described. and represented in the following specification and the acoom panying drawings, forming a part of the same. I This invention relates to an improved fire proof floor, ceiling, or similar "construction of that class in which a filling of concrete or similar plastic material is applied in oonncction withreticulat'ed metal to form a web ex- !5 tendingfrom beatnto beam,'and isespecinlly intended for floor constructions curved in arch form frombesm to beani, although it is applicable also in connection with horizontal or flat arch constructions. 1 so In the production of curved-arch floor constructions, such as shown in prior Letters'Patent Nos. 425,245, 582,807, and 644,913, in whichiarched rods are used to support the lathingand usually woven into the bathing so is as to extend longitudinally of the lathingsheets or frombeam to beain, it has heretofore been usual to draw the successive sheets of lathing togcther,'so as to tie the outerrods of adjacent sheets to each other. These rods are usually seven to nine inchesapart, and this wastes a considerable amountof latbing,

in some cases artotal of several inches intwo' sheets. I In connection With'thcsc arched rods also two or more stay-rods cxtendinglongitudinallyof the arch are usually employed, these being tied to the lathing-rods, so as to hold the rods in place and prevent the arch being thrown out of form by the sheets tilting longitudinally of the arch under the weight 49 of the concrete in making the construction.

The present invention avoids this waste of lathing and use of the stayrods running across the sheets of lathing, while at the same time providinga metal structure of increasedstrength for receiving the concrete, and, moreover, enables the structure to be built much more rapid] y and with greater certainty of proper construction than by tying the lathing-rods together and applying the stay-rods 50 as heretofore. I secure those results by the use of spanner-s, which are 'inadeof suitable" length to embrace the outsider-eds of two ad- I jaceut sheets of laihing, and-secured to these rods, preferably by bending the ends of the spanners aboutthe rods, sons to tie the rods together. These spannors are'applied so that the body of the spanner is below the lath'ing', and the portions of the lathingnt the edges ,of adjacent sheets between lathingwods;

are thus supported-by the spauuei's. If the o lathing-rorls are on the under side of the lathin'mthespanncrs are preferably bent up- "ward near their ends, so that the portions of the spanner-s between the lathing-rods will act to support the edges of the lathing-sheots without sagging of the latter. i

Fora full understanding of the invention; a detailed description-of a construction cmbodying thesavneas applied in its preferred form in connection with a curved floor construction similar to that shown in United States Letters Patent No. 644,913 will-now be given, in connection with the accompanyi'ng drawings, forming a pnrtof this specificzv' tion, and lhefeatu res formingthe invention will then bespeoiiically pointed out in tho claims-.- l In the drawings, Figure l is asection of a. complete floor construction 'em body-*ingtho invention, a suspended ceiling of-common form being shown 'in pon'necti'on therewith. Fig:- 2- is. a plan view of the melml-worh, showing the junction between adjacent sheets Fig is a cross-section on the line 3 of Fig. 2. Fig.1. 4 is a section similar to Fig. 3, showing the preferred form of construction with heavy lathing-rods or rods on the under side of the lathing. v v Referring vto said drawings, A represents the floor-beams, shown as of the common I form; Bpthc lathing; G, the lathing-rods; D, the spnnnors, and E the filling of concrete or similar plastic material. A suspended ceiling F is shown supported by hangers from the bottom flanges of' the beams, as common in such constructions; but this is innnatcrial so far as the present invention is concerned. i

It will be seen froin Figs. 2 and 3 that the spanners D embrace the ceiling-rods 0 next the edge of two adjncontsheets oi lnthing B,

v 3'0 v n ,bends sttheirjouter ends to receive the lath- In Fig. '41 have shown a construction which will preferablybe used where the thickness of thela-thing-rods or. the manner in whichthey are applied to or woven into the li thing that extendbetween the ceiling Jrods are Rbroughtxinto position to support the edges of the'brosder features of the invention. may be applied iii-connection with any-desired form -'thereto"; as a Ye described, and. such corn i spanners extend along the under side of the with the ends of the span ners extending upalso drswing the sheets of lsthing together,

' woveninto the-b0 y'of-the lathing, so as to 11ers consist of straight bars, with their ends,

position 'on the spe'n ners. In this construe .floor'andeeil-ing constructionit may-be, used and thus tie these rods together, an d that the lathing, and 'thussupport the edges of the sheets of lathing as the concrete is filled in. These spafiners are put inplace from above by passing them down through the lat-hing and then upward around adjacent rods 0,

word through-the lathing, as shown in dotted lines in Fig. 3. A suitable bender is then applied to the ends of the spanner-s, and these are bent down-over the ceiling-rods, as shown in full lines in Fig. 3,-this bending operation making s firm and rigid construction.

As shown-"in Fi' 3, the .ceilingrods-are extendcentrally of t-he'lathing, and the spanbentover about the 'lathi'ng-rods, so that the edges of the la'thing-sheets will ssg slightly into position tobesu'pported by'the spanners.

is such-that it is important to avoid the-sagging of the edges of the lathing-shee'ts into tion the sptmners are formed with downward ing-rods, so'that the-portions of thespanners the lathing-sheet's without sagging.

' It will be understood that while the present invention is-especially intended for curved also in 'connection'with horizontal orflatsrch constructions.- It will be understood also that struction'sformspecific features of theinvention. i

WhatII claim is y 1. In a floor,-c 'eili ng, arch like, of sheets of reticulated metal extending from beam to beam, and metal spanpers extending across the'edgcs ofadjacent sheets with their ends extending through and so:

2. In a floor, ceiling, arch-"or similar-conor 'si-milar con-. 'struction', the combination with beams or'the struction, the combination with beams or the like, of sheets of reticulated metal extending from beam to beam, supporting or strengthening rods for said metal extending from beam to beam, and metal spanners extending across the edgesofadjacent sheets below .the metal withthein ends secured to rods of the edi s-,1

cent sheets, substantially as described.-
